Title: Printing head over-current detector in printer
Inventor: KAWAGUCHI TAKEMI
IPC: B41J2/30
Filed: 1989-04-11
Abstract: PURPOSE:To discriminate a variable electric current value by a method wherein a comparison voltage set value which is set correspondingly to printing data for detecting an over-current is read from a ROM to generate a comparison voltage, and this is compared with a detection voltage which is found by detecting an electric current flowing through a printing head to control the operation of a printing head drive circuit. CONSTITUTION:In a DA converter 3, a digital analog conversion of an inputted set value is conducted to generate a comparison voltage, and the comparison voltage is outputted to a comparison circuit 4. A printing head drive circuit 6 drives a printing head 8 with a drive signal transmitted from a microprocessor 2 to perform printing. A voltage detected in a detection circuit 7 and the comparison voltage outputted from the DA converter 3 are compared with each other in the comparison circuit 4. If the detection voltage, larger than the comparison voltage is judged, a change-over circuit 5 stops the operation of the printing head drive circuit to prevent the operation of the printing head 8. In this manner, an over current can be satisfactorily identified.

Title: Series connection high-voltage semiconductor element
Inventor: IDE TETSUO
IPC: H01L25/07
Filed: 1982-05-31
Abstract: PURPOSE:To prevent degradation due to the generation of heat of a diode in the vicinity of an AC terminal by making the capacitance of the junction section of the diode on the AC terminal side larger than that of the junction section of a diode on the DC terminal side. CONSTITUTION:A large number of diode chips 1a-1n are laminated and fixed, and form a block-shaped laminate connected in series. An anode lead 2 and a cathode lead 3 are each connected on the anode side and the cathode side in the laminate. These chips 1a-1n are combined so that the capacitance of the junction sections of the diodes decreases in succession toward the lead 3 from the lead 2. Accordingly, the share voltage of each diode 1a-1n is equalized, and degradation due to the generation of heat of the diode in the vicinity of the AC terminal can be prevented.

Title: Spectacle frame
Inventor: SAKAI YASUSHI
IPC: G02C5/16
Filed: 1995-04-18
Abstract: PURPOSE: To provide a spectacle frame which has spring hinges in sufficiently strong structure without variation in the length of temples by providing surface pressure metal fittings which are arranged on a core rod slidably in the length direction and pressed against the flat end surfaces of wrap-round lugs by springs. CONSTITUTION: A spring 5 is arranged concentrically at the outer periphery of the core rod 2 coupled with the temple 4. The spring 5 is engaged with the core rod 2 on the side of the temple 4 and energizes the flat end surface of the wrap-round lug 1 on the side of the wrap-round 1 through surface pressure metal fittings 7. The surface metal fittings 7 are covered with a spring cover 11 slidably in the length direction of the core rod 2 together with the metal fittings. The temple 4 itself does not have a mechanism for expansion to and contraction from the wrap-round lug 1, so the length of the temple 4 never varies when the temple 4 rotates, and a feeling of fitting is not changed. Further, neither the core rod 2 nor the temple 4 has a movable part and they are united, so the strength of the temple 4 is high.

Title: Stabilizer for electric power
Inventor: SASAKI MITSUGI
IPC: G05F1/56
Filed: 1979-07-20
Abstract: PURPOSE: To burn off a resistance for a fuse securely in case of a load short circuit, by adding one Zener diode.  
     CONSTITUTION: IN case that a load connected to output terminal 5 is short-circuited and output terminal 5 is held at the earth potential, resistance 2 is burned off by the consumed electric power of resistance 2 to protect the circuit, but transistor 3 has variance of current amplification factor h fe  and the resistance may sometimes be unburned off. To burn off resistance 2 securely without reference to the variance of h fe  of transistor 3, Zener diode 13 is connected in parallel to resistance 9. The voltage of Zener diode 13 is cut off in normal operation and when terminal 5 reaches the earth potential, the diode conducts. As a result, R 9  is considered to be reduced in impedance and electric power consumption W 2  of resistance R 2  increases, so that resistance 2 can be burned off without reference to the variance of h fe .

Title: Optical recording and reproducing device
Inventor: MORIYA MITSURO
IPC: G11B7/09
Filed: 1985-04-30
Abstract: PURPOSE:To prevent recording from left unerased by providing the 1st control means controlling the 1st light beam to be scanned always on an information track and the 2nd control means controlling the 2nd light means similarly so as to stop operation of the 2nd means when the 1st means is inactivated. CONSTITUTION:In operating the 2nd tracking control, some time requires until the control system is made stable and the erasure is started after the system is made stable. Thus, a light source 10 is driven to output a weak luminous amount independently of the necessity of erasure, and the 2nd tracking control is activated when the 1st tracking control is applied. In operating the 2nd tracking control when the 1st tracking control is inactivated, then the 2nd control element is destroyed thereby avoiding the 2nd tracking control when the 1st tracking control is inactivated.
